Its designed to work with the stock bracket, but I made my own.

And here is the ebay number lol...

I have bought 2 or 3 of these units from this particular outifit. Becker did not start out as an ebay seller, but finally started listings. You can tell he does not have a lot of ebay experience... the word "ford" is nowhere in his listing, and this narrows his window of "views" down dramatically.

After owning one of the alternators for about 3 years, it went out on me. I called them, explained the issues, sent it to them, and they sent me a new one for free.... their shipping expense. Becker is pretty good on customer service.

Is there any advantage of switching to an alternator if your car is all stock with all the wiring in good condition?

I never recall having any problems with any car I've had that was equipped with a generator that was still all stock.

Two reasons come quickly to mind... excessive idling. An alternator will charge and give a good supply at idle whereas a generator is almost non-existent. The other would be the addition of accessories that increase the need for Amps across the board at any one given time while you try to recharge your battery also.

google a guy named Randy Rundle or Fifth Avenue Electric... great stuff.

Generators don't seem to last anymore. I went through several rebuilds, from different rebuilders and they all failed in an unreasonable amount of time. I couldn't find anything wrong anywhere. I don't know if it is the skill, or parts or a combination of the two that just isn't available to rebuild them reliably. I switched to an alternator, and nearly 10 years later, no problems whatsoever with the charging system.



It was the same story with starters. The original style, rebuilt wouldn't last. Went with the new aftermarket one from Autoelec, also about 10 years ago and no more starter problems.

For me I'm going from 6v in the '55 to 12v so it just seemed easier to get a 12v alternator. (I didn't have a generator anyway).

Makes sense, especially when converting to 12V.
